T/CASEI 074-2026 Guidelines for risk-based design of pressure vessels
Basic Information
Scope
This document specifies the design guidelines for pressure vessels based on risk. It includes basic requirements such as responsibilities and user design conditions, analysis of damage and failure modes, hazard identification and consequence analysis, risk prevention and control measures, and risk assessment reports. This document is applicable to the following situations: a) Class III pressure vessels specified in TSG 21—2016, "Safety Technical Supervision Regulations for Fixed Pressure Vessels"; b) When the design uses new materials, new technologies, new structures, or new processes; c) When the design or user units deem it necessary. Industrial pipelines, boilers, and other pressure-bearing equipment can refer to this document for implementation.
